About this study

Official title: Ultrasonographic Evaluation of Thoracolumbar Fascia Morphology in Axial Spondyloarthropathy and Controls: A Pilot Study With Clinical Assessment of Myofascial Trigger Points

The goal of this observational study is to evaluate whether changes in the thoracolumbar fascia (TLF)-a connective tissue in the lower back-are related to pain and disease severity in patients with axial spondyloarthropathy (ax-SpA), a chronic inflammatory spine condition. The study involves adults diagnosed with ax-SpA and healthy volunteers of similar age and gender.

The main questions it aims to answer are:

Read more

Is the thickness or shape of the thoracolumbar fascia different in patients with ax-SpA compared to healthy individuals? Is there a relationship between changes in the thoracolumbar fascia and the presence of painful muscle trigger points? Researchers will compare measurements in ax-SpA patients and healthy volunteers to see if differences in fascia structure are linked to pain, function, and disease activity.

Participants will:

Undergo a back ultrasound (non-invasive imaging) to assess the thickness and structure of the thoracolumbar fascia.

Be examined for muscle trigger points using gentle manual palpation. Complete questionnaires and assessments on physical function, quality of life, and disease activity.

Read the detailed description

The goal of this observational study is to explore whether structural changes in the thoracolumbar fascia (TLF)-a connective tissue layer in the lower back-are related to pain, stiffness, and disease activity in individuals with axial spondyloarthropathy (ax-SpA), a chronic inflammatory condition that affects the spine and can cause significant back pain and limited mobility. The study also examines whether these changes are linked to myofascial trigger points, which are sensitive or painful spots in the muscles.

This research includes adults diagnosed with ax-SpA, as well as healthy volunteers of similar age and gender who do not have chronic back pain or spinal diseases.

The main questions it aims to answer are:

Do patients with ax-SpA have increased thickness or irregular structure in the thoracolumbar fascia compared to healthy individuals? Is there a connection between fascia changes and the presence of painful muscle trigger points? Are these findings related to the severity of disease symptoms, such as pain, stiffness, physical function, and quality of life? Does the use of anti-inflammatory or immune-modulating medications affect the presence of these muscle trigger points? Researchers will compare ultrasound and clinical findings between ax-SpA patients and healthy volunteers to determine whether structural differences in the fascia can be used as a non-invasive indicator of disease burden.

Participants will:

Undergo a high-resolution ultrasound scan of their lower back to assess the structure and thickness of the thoracolumbar fascia.

Receive a manual examination to check for muscle trigger points in the lower back.

Complete questionnaires related to pain, function, fatigue, and quality of life.

Share information about their medical history, including the use of medications such as non-steroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), and TNF-alpha inhibitors.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sonographic examination of thoracolumbar fascia, manual examination of MTrPOther

    Patients were positioned in the prone position, with a cushion placed under the abdomen to flatten the lumbar lordosis.

    A 14-18 MHz linear transducer was used for ultrasonographic (USG) evaluation, performed with a GE Logiq P5 ultrasound device (Serial No: GE-114118SU3).

    The USG probe was placed longitudinally at the L2-L3 intervertebral level, 2 cm lateral to the vertical line connecting the spinous processes on both sides, in order to assess the thoracolumbar fascia (TLF).

AxSpA groupThis study included individuals aged between 18 and 65 years who were classified as having axial spondyloarthritis (axSpA), including both radiographic and non-radiographic forms, according to the Assessment of SpondyloArthritis International Society (ASAS) classification criteria. Participants with additional health conditions that could affect thoracolumbar fascia (TLF) morphology or spinal biomechanics were excluded from the study. Exclusion criteria included: History of severe back or lower extremity trauma or surgery, Significant spinal deformity (e.g., scoliosis, kyphosis, spinal stenosis), History of spinal surgery, History of spinal fracture, Malignancy or spinal infection, Neurological deficit due to nerve root compression, Neurological or major psychiatric disorders, Bleeding disorders, Previous lumbar steroid injection or current systemic steroid use, Pregnancy, Disability status or ongoing legal process related to low back pain, Presence of acute systemic infection
Receives: Other: Sonographic examination of thoracolumbar fascia, manual examination of MTrP
Healthy groupParticipants in the healthy control group were age-matched (18-65 years) and selected according to the same exclusion criteria applied to the patient group.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ultrasonographic Assessment of Thoracolumbar Fascia (TLF) Thickness

    Thickness of the thoracolumbar fascia (TLF) will be measured using musculoskeletal ultrasound at the L2-L3 vertebral level, bilaterally.

    Unit of measures: millimeters (mm)

    Measured: Baseline (Day 1)

  2. Thoracolumbar fascia morphology

    The morphology of the thoracolumbar fascia will be evaluated bilaterally as either regular or irregular based on ultrasonographic appearance at the same level.

    Unit of Measure: Categorical (Regular/Irregular)

    Measured: Baseline (Day 1)

  3. Presence of myofascial trigger points

    Presence or absence of myofascial trigger points will be assessed through standardized manual palpation criteria during clinical examination.

    Unit of Measure: Binary (Present/Absent)

    Measured: Baseline (Day 1)

Secondary outcomes (2)
  1. Correlation between thoracolumbar fascia thickness and presence of myofascial trigger points

    A correlation analysis will be performed between thoracolumbar fascia thickness (measured in mm via ultrasound) and the presence or absence of myofascial trigger points (determined by physical examination).

    Measured: Baseline (Day 1)

  2. Correlation between thoracolumbar fascia morphology and presence of myofascial trigger points

    A correlation will be evaluated between fascia morphology (categorized as regular/irregular on ultrasound) and the presence or absence of myofascial trigger points.

    Measured: Baseline (Day 1)
